The Democratic National Committee is reportedly asking its staff to submit resignation letters as new chairman Tom Perez launches a major organization overhaul.

Immediately after Perez's selection in late February, an adviser to outgoing interim chair Donna Brazile, Leah Daughtry, asked every staffer to submit a letter of resignation dated April 15, NBC News reported.

The news outlet reported interviews of staff are already under way.

In a statement, Perez spokeswoman Xochitl Hinojosa characterized the move as a typical part of any leadership transition, NBC News reported.

"This is longstanding precedent at the DNC and has happened during multiple chair transitions," she said. "The process was started before the election of the new chair. From the beginning, Tom has been adamant that we structure the DNC for future campaigns. Current and future DNC staff will be integral to that effort . . ."

In the wake of Hillary Clinton's defeat by President Donald Trump, and Democrats' failure to get a majority in the Senate, the DNC has been criticized over the leadership of former chair, Rep. Debbie Wasserman Schultz, D-Fla., as well as the role Clinton's campaign played in running the party last year, The Hill reported.

Next month, it begins work on recommendations on a number of issues, including changes to the nominating process as well as broader questions about how to reorganize the party structure to make it more competitive, The Hill reported.
